How one would go about making one? Do I need 2 of the exact same hard drives?
Above all what's the advantage of it?
Thanks!

Yes, a minimum of 2 identical drives.
It depends on which RAID level you want.

Different levels offer more advantages.
Redundancy (to prevent data loss & corruption) as well as a much higher file access speed in multitasking environments are the primary advantages.

You need 2 of the same drives, plus an add-in card or a motherboard that supports raid. Add in cards from Promise technology are popular. You can raid 2 ATA or 2 SATA drives, depending upon the interface.
With 2 drives you have the choice of raid-0 or raid-1.
Raid 1 is disk shadowing, meaning that both drives are mirrors of each other. If one goes down, the other maintains the system. The added advantage is that data reading is optimized because there are twice as many heads under the data and the read can be accomplished faster.
Raid 0 is disk stripping, in which both physical drives are bound as one virtual disk volume. The disk cylinders are interleaved, meaning that each volume disk track combines the same tracks on each physical drive. There is no redundancy or protection here with 2 drives, all you get is a single volume that is the combined storage capacity of both drives. If you lose one drive, the entire volume is toast.

it would want to do it immediately. It relies upon on the age of your equipment and once you've the most present day BIOS replace put in. In my case, I run a RAID 0 array w/250GB drives, a millionpersistent failed, I reinstalled the newpersistent yet mandatory to rebuild the entire array because of it being RAID 0. on your case it would want to properly be distinct.

yes the drives need to be the same size.
there are different types of raid, but for the most part you get either speed, redundancy or increased capacity.
